Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize a...
Usage Guidance
This package appears to do what it says: templating, validating, and packaging skills. Before running any bundled script: 1) review the Python files (init_skill.py, package_skill.py, quick_validate.py) to confirm file paths and behavior are acceptable; they perform filesystem writes and create zip archives, which is expected but should not be run on sensitive directories. 2) Note that some referenced tools (e.g., eval-viewer/generate_review.py, 'claude-with-access-to-the-skill') are not included — verify or obtain those separately if you need that functionality. 3) The source/homepage is missing and owner IDs in registry vs _meta.json differ; if provenance matters, ask for the upstream source or a signed release. If you plan to execute scripts from this skill, run them in a sandbox or review them first.
Capability Analysis
Type: OpenClaw Skill Name: rex-skill-creator Version: 1.0.0 The bundle is a comprehensive meta-skill designed for creating, testing, and optimizing other OpenClaw skills. It includes utility scripts for scaffolding new projects (init_skill.py), validating metadata (quick_validate.py), and packaging bundles (package_skill.py). The SKILL.md instructions provide a structured workflow for iterative development, benchmarking, and human-in-the-loop review, and explicitly include a 'Principle of Lack of Surprise' that forbids the creation of malware or unauthorized access tools.
Capability Assessment
Purpose & Capability
Name and description (skill creator / iterate & evaluate skills) match the included artifacts: SKILL.md explains authoring/iteration workflows and the repository includes helper scripts to initialize, validate, and package skills. Required env vars/binaries/config paths are none, which is appropriate for a generic authoring tool. Minor metadata mismatch: registry Owner ID (kn7d7p6...) differs from _meta.json ownerId (kn7ajm25...), which is inconsistent but not inherently malicious.
Instruction Scope
SKILL.md stays within the expected scope (interviewing users, drafting SKILL.md, running tests, iterating). It references running validators and an eval viewer (e.g., eval-viewer/generate_review.py) and the model alias 'claude-with-access-to-the-skill' — some referenced tooling/scripts are not bundled here. The instructions also assume the agent or user may execute the included scripts; those scripts perform filesystem operations (create directories, write files, create zip archives). This is expected functionality but means you should not run them on sensitive paths without review.
Install Mechanism
No install spec is provided (instruction-only with bundled scripts). That has low install risk. The included Python scripts are standard utilities; nothing is downloaded from external URLs or installed automatically. No suspicious install behavior detected.
Credentials
The skill declares no required environment variables, credentials, or config paths. The included code does not reference secrets or external credentials. This is proportionate for a skill-authoring tool.
Persistence & Privilege
Flags are defaults (always: false, agent-invocable allowed). The skill does not request persistent/system-wide changes or elevated privileges. The risk here is ordinary: executing the provided scripts will write files to disk (by design) — that is expected for a skill-creator tool.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install rex-skill-creator
  3. After installation, invoke the skill by name or use /rex-skill-creator
  4. Provide required inputs per the skill's parameter spec and get structured output
